Improving colors/brightness in biology image.

Ok, after many hours of tests I had to do everything again, with more controlled light conditions. Now the images are much better, but of course it was quite a lot of work :=( Thanks for your patience guys!

The mentioned color deconvolution plug-in is from 4N6site.com (check out some examples here).
Previous posts contain outdated links, but the plug-in is available through 4N6site.com.
You can also contact the site if you want to be absolutely sure you get the maximum out of the plug-in!
